A new threshold signature scheme based on fuzzy biometric identity

A New Special Biometric Identity Based Signature Scheme

We propose a new special identity based signature scheme that make uses of fractal transform and entropy arrangement algorithm to generate the public key string from a biometric measurement of signer. A biometric reading provided by the alleged signer would be enough to verify the signature. The characteristic of this scheme is that When verifier finished the verification on the signature, he c...

A Biometric Identity Based Signature Scheme

We describe an identity based signature scheme that uses biometric information to construct the public key. Such a scheme would be beneficial in a legal dispute over whether a contract had been signed or not by a user. A biometric reading provided by the alleged signer would be enough to verify the signature. We make use of Fuzzy extractors [7] to generate a key string from a biometric measurem...

A new identity based proxy signature scheme

A new identity based proxy signature scheme Bin Wang Information Engineering College of Yangzhou University Yangzhou City, Jiangsu Province, P.R.China Tel: 086-0514-82220820 E-mail:[email protected] Abstract: Proxy signature schemes allow a proxy signer to generate proxy signatures on behalf of an original signer. Mambo et al. first introduced the notion of proxy signature and a lot of researc...

Biometric Identity Based Signature Revisited

In this paper, we describe a new biometric Identity Based Signature (IBS) scheme based on the Sakai Kasahara Key Construction and prove its security in the framework of a stronger security model compared to exisiting adversarial models. Besides, we present a new type of a denial of service (DoS) attack and evaluate existing biometric IBS schemes in this context. Based on the recently defined pr...
